1. An apparatus for controlling a motion of a vehicle supported on steered and non-steered road wheels, comprising:

  • means for sensing vehicle operating conditions including steering angle and vehicle speed;

    means for calculating a target vehicle motion value based on the sensed steering angle and vehicle speed to provide a predetermined response characteristic related to a vehicle plane behavior, the response characteristic having a damping characteristic;

    means for calculating a target steering angle value for the non-steered road wheel to realize the vehicle plane behavior according to the target vehicle motion value;

    means for steering the non-steered road wheels according to the calculated target steering angle value; and

    means for decreasing the damping characteristic as the sensed vehicle speed increases.
